Скачать или смотреть The Approval That Killed 114 People | a Short Documentary

This video explores the 1981 Hyatt Regency walkway collapse in Kansas City, a turning point in American engineering history. Through a clear, step-by-step look at the original design, the last-minute hanger rod change, and the approval process that followed, it examines how a small structural revision led to a catastrophic failure that killed 114 people and injured more than 200 during a summer tea dance. Drawing on historical records, engineering reports, and eyewitness accounts, it shows how a tragic combination of design decisions, miscommunication, and missed warnings came together on a single July night.

More than a story of a single disaster, this documentary-style video looks at how the collapse reshaped building codes, professional ethics, and the practice of structural engineering in the United States. By tracing the roles of the design firm, the fabricator, and the reviewing engineers, it highlights how responsibility was shared, disputed, and finally judged, and how this event continues to influence how large public structures are designed and reviewed today.
